Junior UI & UX Desgienr / Co-founder

Company • Trabajador autónomo

Dec 2015 - Dec 2016 • 1 yr

As a co-founder and UI Designer, I designed the entire mobile app interface (iOS & Android) from scratch—covering everything from wireframes and high-fidelity mockups to prototyping, visual identity guidelines, and a foundational design system. This journey provided invaluable hands-on experience: managing a real-world project, collaborating with developers, making design decisions within technical and business constraints, and rapidly iterating based on user feedback. Although the project lasted only a year, this initial experience was incredibly formative. It gave me the solid foundation and confidence needed to pursue a career in UI/UX design, while exposing me to the realities of mobile product development right from the start.
